What is the difference between cabernet franc and Cabernet Sauvignon?

Answered by Charles Pate

As an experienced sommelier and brewer, I have had the pleasure of exploring the nuances and differences between various varietals. When it comes to Cabernet Franc and Cabernet Sauvignon, there are several key distinctions that set them apart.

1. Body and Flavor Profile:
Cabernet Franc is generally lighter-bodied compared to Cabernet Sauvignon. It tends to have a more delicate and elegant structure, with softer tannins. On the palate, Cabernet Franc often exhibits herbal and floral notes, such as green bell pepper, tobacco, and violet. This varietal is known for its aromatic qualities and can have a slightly spicy character.

In contrast, Cabernet Sauvignon is more full-bodied and robust. It has a denser structure with firmer tannins, lending to a bolder mouthfeel. Cabernet Sauvignon is often characterized by flavors of blackberry, black currant, cherry, and sometimes even hints of cedar or vanilla. It offers a rich and complex profile, making it a popular choice for those who prefer full-bodied red wines.

2. Aging Potential:
Another difference between these two varietals lies in their aging potential. Cabernet Sauvignon is known for its ability to age well, developing more complexity and depth over time. When properly cellared, it can evolve for several years, with some high-quality Cabernet Sauvignons reaching their peak after a decade or more.

On the other hand, Cabernet Franc is typically enjoyed at a younger age. While it can benefit from some aging, the fruity flavors and vibrant characteristics of Cabernet Franc are best appreciated within a few years of bottling. This varietal is often enjoyed for its youthful charm and freshness.

3. Regional Differences:
Cabernet Franc and Cabernet Sauvignon are grown in many wine regions around the world, each offering its own distinct expression of the varietal. In Bordeaux, France, both varietals are often blended together, with Cabernet Sauvignon dominating the blend. This creates a well-structured and age-worthy wine.

In the Loire Valley of France, Cabernet Franc shines as a single varietal wine, particularly in the sub-region of Chinon. Here, the cooler climate allows Cabernet Franc to develop its herbal and floral characteristics, resulting in lighter-bodied and elegant wines.

In the New World, particularly in regions like Napa Valley, California, and Washington State, Cabernet Sauvignon takes center stage. The warmer climates in these regions allow for riper fruit flavors and higher content in the wines. However, Cabernet Franc can still be found as a standalone varietal or used in blends to add complexity and balance.

While both Cabernet Franc and Cabernet Sauvignon come from the same family of grapes, they offer distinct experiences. Cabernet Franc is lighter-bodied with herbal and floral flavors, while Cabernet Sauvignon is more full-bodied with blackberry and cherry notes. Additionally, Cabernet Sauvignon has a greater aging potential compared to Cabernet Franc. Exploring the differences between these two varietals can be an exciting journey for wine enthusiasts, allowing them to appreciate the range of flavors and styles that the world of wine has to offer.
